(01.vo-zo) My invention relates to certain novel improvements in a combinedhandle and lock and has for its principal object the provision of anim-. proved construction of this character which will be highlyefllcient in use and economical in manufacture.

Without myself to the use or application of my combined handle and lock,in order to illustrate the advancment which I have made over the'artrelating thereto, I makereference hereinafter to the use andapplication of. my invention to the door of a locker such as is employedin school buildings, workshops, oilices and other like places.

' With this in mind, one of the salient objects ofthe invention is toprovide a combined handle and lock, the latter of which will control theoperation of latch lifting mechanism operable by the hand of theoperator upon graspingthe go handle and exerting a slight upwardpressure upon the lifting mechanism to lift' the latch bolt or platefrom its keeper plate or opening.

A still further object of the invention is to provide a combined handleand lock which is self- 26 locking upon closing of the door withwhich itis associated.

A still further object of the invention is to provide a loclathemechanism of which may be independently operated by either a permutation30 "lock or a master key. i

A still further object of the invention is the provision of acombinedtlock and handle which.

when associated with a door having a liftable latch bolt or plate,operates in -a plane parallel with the movement of the l tch bolt orplate thepart of the lifting mechanism and/or the latch boltor platethereby avoiding undue wear as well aspermitting the lifting mechanismto be operated by a'minim'um pressure of the hand against the liftingmechanism thereby eliminating the possibility of the latch bolt or plateand its lifting mechanism being thrown out of alignment with respect toeach other and with respect to the keeper plate.

A. still further object of the invention is the provision of liftingmeans for a latch plate or f member which is in direct connection withthe 7' latch plate or member thereby assuring efficient 50 andexpeditious operation of the entire mech- Other objects willappearhereinafter.

i, 7 Construction inner face of this flange is a plate or latch bar I2.40

This .connection between the plate I: and flange I i is accomplished inthe usual manner by means of slot and pin connections I3.

At predetermined points upon this plate II are provided spaced latchfingers It adapted for engagement with keeper plates l5 secured to theadjacent side jamb it of the cabinet or locker.

Secured to the plate I! is a laterally extending arm i'l having formedtherein an opening i8 which is disposed in registration with anelongated slot l9 formedin the door.

The plate I! and arm I 'I are associated with v the door in the mannerabove explained so as to gravitate into position to dispose the latchfingers II in latched engagement with the keeper 5 plates l5 when thedoor is in completely closed position.

I have selected a door of this structure to illustrate the advantagesand utility of my improved combined handle and lock.

My improved combined handle and. look as shown particularly in itspreferred form of con: struction in Figs. 1 to 6, inclusive includes ahandle 28 the upper end of which is formed to provide a casing orhousing 2| within which the lock mechanism to be presently described isconfined.

To completethe handle there are provided extended portions or ears 22and 22 which are perforated as at 22' fonthe passage of connectingelements 24 preferably in the form of nut receiving 1101a.

These connecting elements 24 are utilized for connecting the handle tothe door III as best. showninFigs'.'7and 8.

The rear portion of the casing or housing 2| is open and when the lockmechanism is assembled therein this open rear portion is normally closedby a plate 25, parallel to" which is slidably arranged a lift" 28.

This 11a :6 includes a horizontally extending portion 21 at its lowerend, and from which lower end also extends a web or'latch'portion 28 forreasons hereinafter-more fully understood.

"u and arranged inthis Extending-laterally from the lift 28 is a pin 28which is adapted for operative projection through the elongated slot I 8formed-in the door. the inner end of the pin 28 fitting into ing |8 ofthe arm I1 of-the plate l2.

The lock mechanism is obviously concerned with the locking of this lift28 against operation and this mechanism will now be described in detailthe open- The casing 21 in its front wan is provided with 40 -'anopening 28; Rotatably mounted in this open-' ing 28 isa knob 21 having abeveled body portion 22 which bears a dial 22 including numericalcharacters and indicating lines 24.

The knob 2| is provided with an annular flange "which is arranged withinthe opening 28 and extends around the marginal edge 28 of the latter(Fig. 3). a

Formed integrally with the knob 2| is a sleeve sleeve 21 is a barrel 'orcylinder 28.

V Secured to the closure plate 25, as by rivets 25'. is a supportingstructure 28 from which is supported the barrel 28 as shown at. Mountedupon this barrel 28 forwardly of the supporting structure plate 38 arethe permutation discs 4|. The discs 4| are of the usual well knownconstruction and include the combination changing rings or keys 42together with the means 42' for rotating the permutation discs about thebarrel 28 so as to permit operation of the lift upon-placing thepermutation discs in proper registration pursuant to a predeterminedrotatlve movement of the dial 2|22.

Hie peripheral edges of the discs 4| are provided with notched outportions to provide a shoulder '42 into which is adapted to be engaged aspring urged pawl 44 which is pivotaliy mounted on the lift 28 as bestshown in Figs. 5, 5', 6' and 8!. The function of this pawl which isnormally urged by a spring 88 in a counterclockwise direction. Figs. 8and G's-will bemade more apparent hereinafter.

Pivotally supported by the supporting structure 88 is a member 45 whichhas formed therein at member 45 is urged, by a spring 85, Fig. 6 in adirection (clockwise, Fig. 6) to project its lateral extension 41 intothe notches 48 inthe discs 4| when the latter are registeredwith eachother.

Formed in the lift 28 is an elongated slot 28' through which a pinill-which is supported by the plate 25 projects, and pivotally supportedby this pin 58 is a latch arm 5|.

This latch arm 8| is normally urged by a spring 58' (Fig. 6") intoposition to dispose the lower end portion 52' thereof into obstructingposition or latching engagement with respect to the web or latch portion28 of the lift 28.

The latch arm 5| includes an upper end portion 52 and this upper endportion 52 of the latch member 5| includes a shoulder 52 which isnormally disposed, by action of the spring 88', in a position to engagean extended portion 54 of the pivotal member 45, for reasons which willbe best understood hereinafter.

The upper endportion52 of the latch member 5| is provided with a concaveshoulder or recess 55 which is adapted to be engaged by the nose portionor rise 58 of a cam 51 which is mounted upon a shaft portion orextension 58 of a lock cylinder or barrel 58, which is rotatably mountedwithin the lock cylinder 28 and within which a plurality of tumblers 88are mounted, these tumblers 88 being-codified to a service or master key8| which controls the operation of the lock cylinder 58 and consequentlythe operation of the shaft 58, as best shown in Fig. 3. g

' The lift 28 is normally urged into a lowered position with respect tothe supporting plate 28 by means of a spring 82 'whichis supported uponthe plate 25 by a pin 88, one end portion 84' of the spring 82 beingdisposed over the upper end portion 84 of the lift 28 as best shown inFig. 8 Carried by the lift 28-and projecting laterally therefrom is apin 82' which is adapted to engage in the recess 48 which is formedin'the pivotal member 45, for a reason to be explained presently.

of Fig.8a with its nose portion or rise 58 extending upwardly and thelift 28 and the latch pin 28 carried thereby are normally prevented frombeing raised or lifted, to effect the door unlatching operation, byreason of the fact that the lower end portion 82' of the pivoted latchmember 5| is normally disposed directly above the transverse web or stopportion 28 of the lift 28, as shown in Figs. 6 and 611. However, aswill.now be described, the operator may move the lower end portion 52'of the latch member 5| out of vertical alignment with the stop portion28 of the lift 28 in either of two ways, that is, either by manipulatingthe combination knob and dial 2 |-24 and the permutation discs 4| intoposition to register the notches 48 in the discs 4| with each other; or;by insertand the permutation discs 4|, are manipulated 15"" intoposition to register the notches so in the permutation discs 4| witheach other, ,the spring 85 acts upon the member 45 to pivot the latter(counterclockwise, Fig. 60;) so as to move the projecting portion 41 ofthe member .48. into the registered or aligned notches 48 in thepermutation discs 4|. v

During this movement of the pivotal member 45 (counterclockwise, Fig.6a) the lower end portion 54 thereof engages the upper end portion 52 ofthe latch member 5| and pivots the latter against the action of itsresetting spring 88', (clockwise, Fig. 6a) so as to dispose the lowerend a portion 52 of the member 5| out of ,alignment with the transverseweb or stop portion 28 of the lift 28, (as in Fig. 6b) therebypermitting the lift 28 to be raised; and when the lift 28 is lowered,

or. reset into its initial position, the spring 88' tion of Fig. 6a toits position of Fig. 617) so as to dispose thelower end portion 52'thereof out of I alignment-with the stop portion or web 28 of thelift,28 by insertinga proper key 8| into the lock cylinder or barrel 5!and then turning the same v and the shaft 58 and cam 51 (clockwise, Fig.6a)

This movement of the lock cylinder 58, shaft 58 v and cam 51 (clockwise,Fig. 6a) causes the nose portion or rise 58 of the-cam 51 to engage theshoulder 53 which is formed in the upper end portion 54 of the latchmember 5|, thereby pivoting the latch member 5| (clockwise, Fig. (in) soas to dispose the lower end portion 52' thereof out of alignment withthe web or stop portion 28 of the lift. 28 so that the latter may belifted. The key 8| may then be manipulated so as to turn the lockcylinder 58 shaft 58, and cam 51 (in a counterclockwise direction, Fig.6a) back'into their initialpositions. when the permutation discs 4| aremanipulated, bythe knob and dial 3l34, into position to register thenotches 48 therein, the notches 43 in the permutation discs 4| are alsoregistered. Accordingly, after the lift 28 has been raised, to performthe door-unlatching operation, and is being returned by gravity to itslowered position,

the spring 88 acts upon the pivotal member or pawl 44, which is carriedby the lift 28, to urge the lateral extension 81 of the member .44 intoen- "gagement with the peripheral edges of the discs 4 I therebydisposing'the extension 81 of the mem her in the aligned notches 48which are formed I clockwise direction, Fig. 6a).

in the peripheral edges of the permutation discs 4|, as shown in Fig.50. As they lift 28 continues.

its downward movement, the lateral extension 81 of the member 44,engaging in the notched portions 48 of the permutation discs 4|, turnsthe latter (clockwise, Figs. 5 and 5a) whereupon the cam edges 13 of thediscs 4| which define one marginal wall or edge of the notched portions48 (Fig. 5a), engage the lateral extension 41- of the member 45 andtherebypivot the member 45 (in a movement of the member 45 moves thelater thereof out of the notches 48 in the permutation discs 4|,whereupon the discs are rotated or moved further, in a clockwisedirection, Fig. 5d,

by the lateral extension 81 of the pawl 44. In this manner the relativepositions of the discs 4| are changed, that is, the notches 48 are movedout of registration with each other, and with the '|4 on the slide bar|2 into latching engagement extension 41 lateral extension 41 of themember 45, and the combination is destroyed or scattered, so that thedevice can not again be operated by means of the dial 8 8, until thepermutation discs 4| are again manipulated, by a person knowing theproper 5 combination, into position to register the notches 48 with eachother and with the lateral extension 41 of the latch member 48.

During the downward movement of the lift 28 the pin 88' carried therebyengages in the recessed portion 48 of the pivotal member 45 and therebypivots the latter (clockwise, Figs. 6' and 6a) so as to dispose its endportion 54 out of engagement with the shoulder 53 of thelatch 5|.

It is to be noted, however, that even though the 15 device can not againbe operated, by means of the knob 3|, until thesame is operated by a person knowing the proper combination, it may, nevertheless, be operated bythe insertion of a proper key 8| into the lock cylinder or barrel 88. 2Attached to the door l8 on the inner side of the latter is a piece offlat spring metal 88 which has an angled upper end portion 18 and thisangled upper end portion 18 of the member 88 is engageable when the doorI8 is in opened position, with a serrated edge portion 1| which isprovided in the slide bar l2 so as to hold the slide bar |2 in raisedposition when the door I8 is open, and likewise holding the main latchmember or lift 28 in effective or latching posi tion, when the door I8is in opened position. However, when thedoor i8 is closed an angled endportion 12 of one of the keeper plates l5 (Fig. 9) engages'the angledend portion 18 of the latch member 88 and forces the angled endportion18 of the latch member 88 out of latching engagement with theserrated edge portion 1| of the slide bar l2, thereby permitting theslide bar l2 to drop by gravity and thus moving the lugs 40 with thekeeper plates l5, (Fig. 9).

This downward movement of the slide bar l2 acts upon the pin 29 to movethe latter downwardly in the slot l8 (Fig. -9) which is formed in'theface plate of the door "I, thereby lowering'the lift or latch member 28into its lowered or effective positiomwhereu'pon the spring 88'moves-the latch member 5| into position to dis* pose the lower endportion 52' thereof above the upper end of the-web or stop portion 28 ofthe latch'member or lift 28 so as to prevent unauthorized movement ofthe latter.

It is to be noted that when the lower end portion 52' of the latchmember 5|. is moved out of. latching engagement with the latch portionor r. web 28 of the lift 28, either by means of the key 8| or thedial-bearing knob 3|, the lift 28 may be raised so as to lift the latchbar |2 by-merely grasping the handle 28 and exerting an upward pressureon the lower end portion 21 of the .lift (30 28 by means of the indexfinger, it being noted that the lower end portion 21 of the lift 28 isdisposed within the confines of the handlev 28 and that the handle 28remains stationary relative to the door I 8 during this operation ofraising the 05 lift 28.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification, without departing from the 70 spirit of theinvention, I, therefore, do not wish to be limited to the precisedetails of construction set' forth, but desire to avail myself of suchvariations and modifications -as come within the scope of the appendedclaims.
